The DHT22 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed).

Connections are simple, the first pin on the left to 3-5V power, the second pin to your data input pin and the right most pin to ground.

Technical details:

  • Power: 3-5V
  • Max Current: 2.5mA
  • Humidity: 0-100%, 2-5% accuracy
  • Temperature: -40 to 80°C, ±0.5°C accuracy
